Under SELinux, every process and every object (e.g. file, > socket, pipe) on the system is given a security context, a label which include detailed > type information about the object. The kernel allows processes to access objects only if > that access is explicitly allowed by the policy in effect. The policy defines transitions, > so that a user can be allowed to run software, but the software can run under a different > context than the user's default. This automatically limits the damage that the software > can do to files accessible by the calling user â the user does not need to take any action > to gain this benefit. <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/> > <xhtml:br xmlns:xhtml="http://www.w3.org/1999/xhtml"/> > For an action to occur, both the traditional DAC permissions must be > satisifed as well as SELinux's MAC rules.

The targeted SELinux policy > consists mostly of Type Enforcement (TE) rules, and a small number of Role-Based Access > Control (RBAC) rules. It restricts the actions of many types of programs, but leaves > interactive users largely unaffected. The strict policy also uses TE and RBAC rules, but > on more programs and more aggressively.
